 MongoDB supports the following architectures: arm64, ppc64le, s390x,
 and x86-64. More detailed platform instructions can be found below.
 
-## MongoDB Tools
+## Quick (re)Start
 
-The MongoDB command line tools (`mongodump`, `mongorestore`,
-`mongoimport`, `mongoexport`, etc) have been rewritten in
